Troponin I is a more specific marker for a myocardial infarction compared to the other options listed. AST and LHI can be elevated in many different conditions and are not specific to heart damage, while CK-MB can be elevated in other conditions that cause muscle damage as well. Troponin I, on the other hand, is a protein found specifically in heart muscle, and its elevation in the blood is a good indicator of cardiac damage.
